PH10 motorised indexing heads
Motorised indexing heads allow flexible and repeatable probe re-orientation.
In May 2009 Renishaw introduced a series of design enhancements for its range of PH10 motorised heads, resulting in a 20% improvement in repeatability and increased long term stability.
The range comprises three PH10 models, each of which can carry a range of probes and extensions and can be orientated in 720 repeatable positions, giving access to the most difficult-to-reach workpiece features.
All three variants of the new PH10 heads are now supplied with a revised repeatability specification, down from 0.5 µm (2σ) to just 0.4 µm (2σ) (specified at a distance of 62 mm), giving users improved positioning at the stylus tip. The new specification heads are physically differentiated by a new ‘aqua blast’ finish which gives a modern, matt black appearance.
The PH10M can carry long extension bars and complex probes such as SP25M or TP7M. The highly repeatable autojoint allows rapid probe or extension bar changing without the need for re-qualification.
The PH10MQ is a variant of the PH10M that allows the motorised head to be attached directly to the quill with the B axis of the head inside the quill itself. This option provides a neater and shorter probe mount, with only the A axis protruding from the quill.
The PH10T is similar to the PH10M, except that it features an M8 thread probe mount in place of the autojoint.
All M8 threaded probes, such as TP20 and TP200, and extension bars fit directly onto the head. The PH10T is fully compatible with all of Renishaw's stylus and module change systems.
